Test conditions and notes9

1. All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uF & 47uF parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. Derating may be need under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
5. The Regulatory Compliance Mark (RCM) is applied on a voluntary basis. The equipment meets the relevant IEC or AS/NZS standards, or AS/NZS 3820 where applicable. The use of the RCM mark complies with AS/NZS 4417.1.
6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
7. Some factory or model may not have the BIS logo, please contact your MEAN WELL sales for more information.
8. MOPP is suitable for 100-240Vac input only
9. The ambient temperature derating of 3.5℃/1000m with fanless models and 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

What applications is the Mean Well NSP-150-5 best suited for?

The NSP-150-5 is designed for industrial, automation, telecommunications, and medical equipment where a regulated 5V output is required. Its 150W rating, 30A output current, and high-reliability design make it a strong fit for systems that need stable low-voltage DC power in demanding environments.

What are the main electrical specifications of the NSP-150-5?

This model provides a 5V DC output rated at 30A, with a total power rating of 150W. It accepts a universal 85-305VAC or 120-431VDC input range and includes active power factor correction for efficient operation across a wide input range.

How does the NSP-150-5 differ from a standard enclosed power supply?

The NSP-150-5 is built as a high-reliability unit with features not always found on basic enclosed supplies, including active PFC, remote ON/OFF, remote sense, and a DC OK signal. It also offers 91% typical efficiency, SEMI F47 voltage-sag approval, and a long MTBF above 2,000,000 hours (Telcordia SR-332).

Can the NSP-150-5 be used in harsh or wide-temperature environments?

Yes. The unit is rated for operation from -40°C to +85°C ambient, with output derating at higher temperatures according to the datasheet derating curve, which makes it suitable for industrial environments with significant temperature variation. It is also specified for 20-90% RH non-condensing humidity and 10-500Hz, 2G vibration.

Does the NSP-150-5 support system monitoring and remote control functions?

Yes. This model includes remote ON/OFF control, remote sense with up to 0.3V compensation, and a DC OK signal output for monitoring power status. Those features are useful in higher-end industrial or medical systems that need centralized power supervision.

Is the NSP-150-5 suitable for medical or safety-critical equipment?

It is designed for high-reliability applications and complies with multiple safety standards, including IEC/EN 60601-1 and ANSI/AAMI ES60601-1, with 2xMOPP primary-secondary isolation, earth leakage current below 350μA and touch current below 100μA. That makes it appropriate for medical-related designs where certified isolation and low leakage current are important requirements.
